People, don't mind brendang, the child is so full of his/her/itself that it doesn't realize that this is the optometry forum to begin with, and that there is little benefit gained from insulting every active member of the forum...we should also note that brendang has characterized him/her/itself as the "retina geek"
A geek is defined by dictionary.com as the following...
1. a. A person regarded as foolish, inept, or clumsy.
1. b. A person who is single-minded or accomplished in scientific or technical pursuits but is felt to be socially inept.
2. A carnival performer whose show consists of bizarre acts, such as biting the head off a live chicken.
Now, though it seems brendang fits every description of these definitions, in the assumed case of definition #2, perhaps the adjective "retina" implies he/she/it bites the EYES out of the heads of live chickens. In which case, I motion we ignore any further comments made by the aforementioned circus freak on this forum as there is no benefit in responding. (sorry cpw, I had to make the motion to help keep this forum contained).
